MULTIPLE ANTISKID RIBBED SUCTION SOLE FOR SHOES AND RUBBER FOOTWEARFiled June '9, 1945 Fitz-35.2.

INVENTORQI E175ZI54H06= Patented July 22, 1947 SOLE FOR SHOES WEAR ElsieClaire Hogg, ,NIJ. Application June 9, 1945, seri ii messages Thisinvention relates to an improved antiskid shoe sole, and one of itsobjects is to provide a shoe sole or rubber footwearwith a plurality olmolded suction cups and an area surrounding each skid cup which isprovided with skid resisting integral ribs, the ribs extending indivergent or non-parallel directions when comparedwith the skidresisting ribs ofad acent areas, so that some of the skid resisting ribswill be in angular relation to any sliding movement of the shoe, andwill thereby effectively resist skidding or slipping of the shoe on ,iceor ice covered pavements, or upon other slippery surfaces.

With the above and other objects in view the invention comprises certainnew and useful con structions, combinations, and arrangements of parts,clearly described in the following specification, and full illustratedin the accompanying drawings, in which- Fig. 1 is a bottom plan view ofthe improved sole for shoes or rubber footwear.

Fig. 2 is a transverse sectional View, taken on line 22 of Fig. 1,looking in the direction of the arrows.

Fig. 3 is a similar view, taken on line 3-3 of Fig. 1, looking in thedirection of the arrows.

Referring to the accompanying drawings, which illustrate the practicalembodiment of my invention, 5 designates the body of the sole for shoesor rubber footwear, which is constructed of natural or synthetic rubber,or compositions which include rubber, or any other suitable material.

The sole is constructed with a heel part 6 and a foot supporting part I,which are separated from each other by the neutral shank or connectingpart B.

The heel engaging or supporting part 6 is formed with one or more rubbersuction cups 9, which includes the circular rim portion 9a. and theconcave socket portion 9b. The outer surface of the circular rim portionis disposed flush with the tread surface of the heel part. The area [0surrounding the suction cup 9 is formed with intersecting molded skidresisting ribs H and I2, which extend at right angles to the main axisof the shoe sole and at right angles thereto, and therefore at rightangles to each other. Those intersecting skid resisting ribs therebyprovide small rectangular suction cups l3, in considerabl number, aroundthe main suction cup 9, and make up a tread surface which will yieldslightly in all directions to resist sliding, and which will develop asuctional pull upon any wetted or slippery surface, which willeffectively oppose free sliding.

4 Claims. (01.36%595 1 The sole part l-is provided atthe forward end ofthe samefwith ajsuction cupl l and a series of pamue skid resisting'molded ribs l5, which extend in the general direction of the lengthofthe sol'e, andon all sides of the cup. Y

. Rearwardly of the group of molded: ribs 15, time other groups it and Hare provided, which are shown 'tocover an approximately equal area,

sov that the dividing line between the twogroups falls at approximatelythe median line of the sole at. 18, "The r'ibs [6a of the group 16 areshown toextend diagonally,and the ribs Ila of the group H are shown tavextend at right angles to the length of the sole. In the center of thegroup It a suction cup 19 is formed, which has the generalcharacteristics of the suction cup 9, of the heel part 6. In theapproximate center of the group H a, suction cup 29 is formed, which isof similar construction.

Rearwardly of the two groups l6 and I1 two additional groups of skidresisting ribs are provided, at 2| and 22. The ribs of the group 2|extend at approximately right angles to the direction of the length ofthe sole, and the ribs 22 extend in the general length of the sole, andat approximately right angles to the direction of the ribs 21.

The impact of the walking step is initially received by the suction cupl4, and then by the suction cups l9 and 20, and the skid resisting ribssupporting the areas around these cups, and the groups '2! and 22 havea. decreasing contact with the ground surface, due to the rise of thearch of the shoe.

In the area of the sole part forwardly of the groups 2| and. 22 threeangular directions are provided for the skid resisting ribs. The forwardribs are disposed on approximately parallel relation to the length ofthe sole, the group lli is disposed in diagonal relation thereto, andthe group I1 is disposed at right angles to the group I5. Thiscombination thus includes skid resisting ribs which will resisteffectively slipping either at right angle to the direction of walking,or in diagonal relation thereto, or in the direction of walking, or inan opposite direction. The groups 2| and 22 increase this measure oflateral protection against skidding.

It is understood that various changes in the details of construction,their combination and arrangement, may be made, within the scope of theclaims hereof,

Having described my invention, I claim as new:

1. A skid resisting sole for shoes and rubber footwear, comprising asole part and a heel part,

the heel part having a suction cup provided with a circular rim havingtread engagement with the ground and intersectin ribs providing aplurality of smaller suction cups of rectangular shape, and the solepart having a plurality of suction cups and skid resisting ribs betweensaid suction cups.

2. A skid resisting sole for shoes and rubber footwear, comprising asole part and a heel part, the heel part having a. series ofintersecting skid resisting ribs, the sole part having a suction cuplocated in the forward portion thereof and a pair of suction cupslocated rearwardly of the first suction cup and in opposition to eachother near the side edges of the sole part but spaced inwardly thereof,the sole part having a series of parallel skid resisting ribs extendingin the general direction of the length of the sole part and surroundinthe first-named suction cup, and further having skid resisting ribssurrounding each of the second-named suction cups and disposed indifferent angular relation to each other and to the skid resisting ribsfirst-named.

3. A skid resisting sole for shoes and rubber footwear, comprising asole part and a heel part, the sole part having a suction cup locatednear the forward area thereof and suction cups located rearwardly of thefirst-named suction cup, the sole part having skid resisting ribssurrounding the first-named suction cup which extend in the generaldirection of the sole part, and the last-named suction CH PS beingsurrounded by s'kid resisting ribs which extend in different an- 4 gulardirections to the ribs at the forward part and in non-paralleldirections to each other.

4. A skid resisting sole for shoes and rubber footwear, comprising asole part having a suction cup located near the tip thereof and providedwith skid resisting ribs extending forwardly and rearwardly thereof andfurther provided with groups of skid resisting ribs located rearwardlyof said first-named ribs and extending in diagonal relation to thefirst-named ribs and at right angles thereto, and further provided witha suction cup located in each of such groups of ribs.
